V's don't give inherently better torque - that is a function of stroke. Longer stroke, more turning moment on the crank.



V's are 'usually' more torquey because a 1000cc V-twin has much longer stroke than a 1000cc I4. A V4 of 81mm bore has the same stroke to an I4 with 81mm bore and thus, the same torque.



Hardleys have a lot of torque and not much power - long stroke, slow piston speed. A GSXR600RR has a lot of power, not much torque - short stroke, high piston speed.



A 1600cc Harley can have a 5" stroke, a GSXR600RR has 1.78" stroke. Try undoing a bolt while holding your spanner 2" from the bolt...

Minor quibble: At a fixed cylinder displacement, piston area and stroke scale proportionally. A bigger piston will give more raw push, but the shorter crank throw means that force will create less crank torque. The two factors offset each other exactly.

All other things being equal, both engines will produce the same crank torque.

No argument from me... I thought I was dispelling the meme that V engines have inherently more torque?

Motegi should be a good track for Ducati, if they have made any real progress it should show there.

Even last year they were not doing bad lap times, but both riders were unlucky in the race.

it will definitely be interesting to see how they go at Motegi, hopefully with all those straights it should be better for the Ducati!

A more female version of those chicks that sook about Stoner whooping Rossi's arse!!



There is actually a modicum of cred. in being a "bopper chick", cos being a real chick, you can actually partially justify why you act like a chick!!

(Rossi)Bopper = Frothing Rossi fan who dislikes any rider who has the gall to challenge him on-track.



The term gets used freely around here and is not to be taken entirely seriously!

Whats wrong with Ducati? after this weekend id say everything,Dovi and Spies say goodbye to your careers that bike is a complete pile.
 
if i was dovi i would have done exactly the same, i defended his decision to try the ducati somewhere on here.

but spies is a total ..... for doing this. except he gets paid multiple millions in order to retire in his 20s to live the best remaining 50+ years one could imagine.

bikez bluntz bitchez ...........!oh and he probably hangs out with colin and casey so thats cool too

I think Dovi is doing the same. he has a wife and kids and money and when he leaves Ducati he will have enough for ever.
 
greedy ......., should have earned enough at repsol. well, good for him. i like him.





edit: but really what other choice did he have?that tech3 seat is not going to take him anywhere except the occasional podium next year,which will be much harder than this year (4 top riders with 4 top crews on the good bikes).and a factory yamaha or honda seat is just totally out of the question if we are being realistic.maybe if the ducati turns out to be as good as it used to be in the 990 era he can at least make him self look better than "just" being a fast consistent rider

He has a kid and an ex-girlfriend. I made the mistake of asking if he'd enjoyed the time with his family over the break, and got a terse lecture on his personal situation.
